As FOX chairman of entertainment Kevin Reilly announced last week, Monteith's character Finn Hudson, will be written out of the show and the storyline will "deal directly with the incidents involved in Cory's passing and drug abuse in particular."

Because the soundtrack for every episode is recorded in advance, it's believed that Michele might have been prepping songs on Monday for this special episode.

While it will be revealed what Michele sang when the show airs Oct. 10, executive music producer Adam Anders did Tweet to her on Monday, "you are the strongest person I know. That was truly amazing. Love you xoxo #leastrong."

Proceeds of music sales from that episode will go toward a fund in Monteith's name.

Fans of Monteith may make donations in his name to three charities that were especially important to him: Project Limelight Society, which exposes youth living in Vancouver's Downtown Eastside to the arts; Virgin Unite, founded to support entrepreneurial efforts to better the world; and , which helps homeless and low-income individuals find employment.
